Beitknown that I, EDWARD F.'KUiurH, a'

citizen of theUnited-States, residing in Jersey City, in the county of Hudson and State of 'NewyJersey, have invented certain new and useful Im rovements in T e-Writing Machines, of w 'ch the-following is a specification.- t Tlns invent on relates to'means for conducting sheets of paper around the platens of type-writing machines, particularly those of the front-strike variety, and. especially where it is desired to insert andremove successive billsor other sheets while a sin le record-sheet,with its carbon, remains in t e machine, so as to receive carbon impresslons of'all the matterwritten upon the successive sheetsgf In this class of (pa er-feeding' mech anism' me'ans are rovi ed for holdln one sheetorset of .s eets against the p aten while othr sheets 'are'introd-uced ateither the front or rear. of the platen and pushed around. under the same untilv proper posi tion for receiving the first line of'writing.

for facilitating the introduction of sheets downwardly at the front of the machine and the movement of such sheets below said paper-fingers, and. I make provision also for preventing the leading edges of the sheets om catc ing the ink-ribbon as the ascend in front of the platen. I also pro.vi e means forward of the first-mentioned a er-shelf for deflecting the leading ed e oFtl ie away from the platen, so t at it may not pass around the platen a second time The outside sheetsthat is, those. which are pushed around the platen outside of or beow said paper-fingersI feed by means of rollsmpunted to bear against the front of the platen above the printin -lin'e or against the upper front side of the aten, such rolls also being efiective to feed t e record-sheets that are passed between the pa er-fi'ngers and-the platen. These front ro s are preferably mounted tandem in pairs, each tandem pair mounted on a truck, and the latter hinged front of the platen. These rollers not onl may bear evenly against the platen at .al'

times, buta sufficient number ereof'is also be moved to release its rolls, so that I a large number of rolls is fprovided ro'm the upon a; spring-pressed arm, WhlCh 1s carried by and adjustable along. a rod mounted in rovided to effect true feeding of the paper, 4 ese roller-bearing farms ,are preferably four in number, thus making .two sets, one set for the-wide record-sheets and the'othe'r.

Fi .1 21a; a rear-view of a pair of scales hinge .infi'o nt of the. laten and liav .jjing pendentapronsf'for gui ingTthe leading edge of the paper and also. having shields for preventing the leading edge of the paper from catching in the ribbon. Fi 3 is a sectional elevation of the pa ereeding devices. arms which carry the front paper-rolls, and Fig. 5 is a sectional view showing the rear pressure-rolls released from the platen.

The platen 1 of said machine is revolubly mounted, by means of an axle 2, in a platenframe comprising ends 3 4 and a rear plate 5. Ty e-bars 6 enter a guide 7 and strike upon the front side of the laten through the usual inking-ribbon 8, ig. 2, which is threaded through a carrier 9. One or more record-sheets, with their carbons, are introduced at the rear side of the platen and lie upon a paper shelf or support 10. Said shelf inclines upwardly and rearwardly from the platen, belng carried by a pair of arms 11, secured by means of a bar 12 to the upper edge of said plate 5. This shelf 10 is of great height, because the record-sheets for which it is used are usually of very great length, and by providing the high support therefor they are prevented from trailing upon the rear portions of the type-writing machine and are kept away from the rear end of other sheets that are in the machine at the same time. Said record-sheets pass down between the platen and a set of pressure-rolls 13, which are carried by the lower ends of depending arms 14, the latter hinged upon a rod 15. The arms are provided with springs 16 to press the rolls a ainst the platen. The arms 14" are releasable by means of a shaft 17, having a release-key 18. Said shaft has a groove 19 normally occupied by the arms 14, Fig. 3, in which the rolls 13 are shown pressing against the platen. When said reease key is depressed, Fig. 5, the recessed portions of said shaft operate to cam the arms away from the platen, thereby leaving the rolls free and permitting the introduction of sheets. The late of metal of which the shelf 10 is formed is shown as cut away alon its lower ortion to form paper-guiding ngers 20, w ich curve past the rollers 13 and down around the laten and up partly in front thereof. Their forward ends may press yieldingly against the platen, Figs. 3,

and 5. Paper-guiding fingers may, however, be otherwise associated with the paper-shelf 10 for the record-Sheets. Said late 5,it will be seen, inclines upwardly and rearwardly from -the platen and corresponds to the paper-shelf usually provided in said Underwood machine. At its lower portion it is continued to form a deflector or uide 21', which curves forwardly and upward y around the platen, but is situated a short distance beneath the said guidin -fingers 20, so as to leave a clear space there elow for the movement of aper, said plate 21 being unbroken or imperforate throughout, so as not to leave .anyedges or projections on which the paper Fig. 4 is a detail 0 the releasable might catch. It will thus be seen that after therecord-sheets are introduced between the shelf 10 and the platen and passed around the latter it is easy to introduce individuals bills or other blanks by slipping them down between the paper-shelf 5 and the pa er-fingers 20 and pushing said bills forwar ly and up around the platen to the printing-line. To the rear side of the shelf 10 I secure a sheath 22, which hangs behind the pressurerolls 13 and prevents the rear sheets when introduced from catching upon said rolls and directs them downwardly along the paper-shelf 5, said sheath 22 extending about the whole length of the platen, as will be understood.

Both the innerland outer sheets ascending in front of the platen are caught between the latter and pressure-rolls 23 24, bearing against the upper front side of the platen. Said rolls are in tandem pairs, each pair carried upon a truck 25, prvoted at 26 on the front end of an arm 27, hung upon a rod 28, the latter fixed at its ends in a pair of arms 29, forming a part of the platen-frame. Each truck is provided with a paper-guide 30, extending from roll to roll, to prevent the leading edge of the paper from catching upon a roll. Said arms are pressed toward the platen by springs 31, bearing upon short rods or keys 32, which fit in a groove 33, formed longitudinally in the bar 28. By grasping a hook or finger-piece 34. provided u on the arm 29 the latter may be swung orwardly, Fig. 3, to release the rolls from the platen to permit the adjustment of aper thereon or the introduction of sheets ownwardly in front of the platen, such movement forcing the keys 32 out of the groove 33, as seen at Fig. 4, and carrying the rolls so far forward as to leave a commodious opening for the introduction of sheets. The arms 27 are adjustable along said rod 28 and are preferably four in number, two middle ones to be used for bills or other blanks or sheets and the two outer ones for wide record-sheets, which, it will be understood, may be provided with margins for the purpose of being enga ed by said rollers.

Fetween the rolls 24 and the paper-shelf 10 I provide a plate 35, which extends from the platen upwardly and rearwardly to deflect the leading edge of the paper directly up away from the platen, so that it cannot go around the latter a second time. Said plate 35 may be supported, by means of a pair of ears 36 and screws 37, upon the ends of the platenframe and is so close to the shelf 10 that the leading edges of limp or thin sheets as they pass upwardly over the plate 35 are caught u on the shelf 10 and do not curl down an reenter the bite of the paper-feeding devices,

Scales 38, one at each side of the typeguide 7, facilitate the adjustment of the paper to the inged upon. rackets 39,pressed rearwardlyby .s rings 40, and incline upwardly andforwar ly from the laten to form a guide whereby sheets may he conveniently introduced downwardly in front of the laten and between the fingers andde ector 21. The,

brackets 39 are fixed u on the framework of the machine so; that t e scales remain stationary, as usual in the Underwood machine, while the platen travels in letter-space direction. As seen in Figs. 1,2, and 3, aprons or shields 4 1, attached to the rear side of said scales, depend in. front of the plate 21 and slightly overlap its front edge, whereby the leading edges of upwardly-advancing sheets are guided and also whereby the leading edges of sheets introduced downwardly at the front of the platen are revented from passing down in frontof sai plate 21,.

The adjacent .ends of shields 41 are pro- ,vided with guards 42 just in rear of the ribbon-vibrator 9 and serving to fend the lead ing edge of the paper away from the ribbonS.

Variations may be resorted to within the scope of my invention, and portions of my 'im rovements may be used without others.
